A golf club head is formed of a hollow metal body having a center of gravity that is above the geometric center of the club face. The hollow metal body of the club head has a sole plate that is smoothly contoured and devoid of any inefficient structures such as weight pads or other mass concentrations. By avoiding the use of inefficient structures such as weight pads, more material is available for the structural walls of the club head body while maintaining the club head within acceptable weight limitations. Moreover, placement of the center of gravity above the center line of the face ensures that sufficient backspin will be imparted to the golf ball when struck by the club.

A golf club head composed of a forged metal material has a striking surface that is supported by diagonal stiffening regions that extend from a central region of the face toward the heel-sole quadrant, heel-crown quadrant, toe-crown quadrant, and toe-sole quadrants of the face. The diagonal stiffening regions are smoothly contoured to blend into the back surface of the face so as to avoid any stress concentrations. By extending the stiffening regions diagonally from the center of the club face to the four quadrants, a more uniform stress distribution can be obtained and therefore more uniform performance. Additionally, since the diagonal stiffening regions are greater in length than vertical or horizontal stiffening region could be made, the center of the face can deflect a greater amount without exceeding the yield strength of the material and, therefore, there is a more efficient transfer of energy from the club head to the ball.

The erogenic stimulator includes a first resilient end region (phallic) extending from a base and a second resilient bulbous end region extending therefrom. The bulbous end is connected via a reduced diameter neck to the base. The base and first and second ends form a truncated substantially U-shaped stimulator. A concave suction element is formed on the base in the curved portion of the U-shape. A passageway may be included from the concave suction element through the base into which may be inserted either a plug or a vibratory element. The plug / vibratory element closes the base end of the passageway thereby permitting expansion and contraction of the passageway dependent upon a predetermined condition at the suction opening of the passageway. If the suction element contacts the skin or an erogenous region and blocks the passageway, the rocking stimulator suctions and evacuates, alternatively, air through the suction opening of the passageway.

The invention discloses a spatial-spectral integrated hyperspectral remote sensing image classification method. A conventional hyperspectral image classification technology mainly focuses on how to use the classification information of spectral spaces better, but ignores the information of image spatial domains. According to the invention, in the process of carrying out self spectral feature classification by using data, spectral classification results are supplemented by using effective spatial domain information combining a region growing method with a binary morphology method. According to the invention, an SVM (support vector machine) based classification method is adopted for carrying out spectral domain classification on data firstly; then, effective spatial domain information is introduced by using the region growing method and the binary morphology method so as to correct spectral classification results. According to the invention, information contained in hyperspectral data is used more fully, and the precision of hyperspectral image classification is improved.
